it's killing me (catching URL passing to Steam)

[Chris green]

i have a basic browser with no buttons loading a web page with Steam links e.g(steam://rungameid/55150)

what i want to do is have the program catch Steam URL's then pass them to Steam

this is what i have so far

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using CefSharp;
using CefSharp.WinForms;
using System.Media;

namespace Steam_manager
{

    public partial class Form1 : Form
    {
        public ChromiumWebBrowser chromeBrowser;
 
        public Form1()
        {
            InitializeComponent();
            // Start the browser after initialize global component
            InitializeChromium();
        }

       
        public void InitializeChromium()
        {
            CefSettings settings = new CefSettings();
            Cef.Initialize(settings);
            chromeBrowser = new ChromiumWebBrowser("https://www.google.co.uk");
            this.Controls.Add(chromeBrowser);
            chromeBrowser.Dock = DockStyle.Fill;

           
        }
        private void Form1_Load(object sender, EventArgs e)
        {
           
           
        }
        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            Cef.Shutdown();
        }        
    }
}
